Conference Call with Shannon Brown
Attendees: Alex Guerrero, Sarah Hanif, Kevin Thompson
What we are working on:
economic evaluation
carbon or stainless steel?
over 800 F cant use carbon
material and energy balance
have an in-progress aspen flowsheet for material balances
will start on energy balances soon
Location: Morris, Il
make sure its close to a railroad so its easy for foxtrot to transport coal.
Send flowsheet to Shannon when done
Next conference call: Thursday, February 10th at 1:00 pm
Discuss time for in person meeting with Shannon
On the table:
Get to Shannon's work after senior design
Friday evenings after 4

Joint Team Meeting: Foxtrot and Echo.
Attendees:
Shannon Brown, Adam Kanyuh
Team Echo: Sabah Basrawi, Sarah Hanif, Kevin Thompson, Mrunal Patel
Team Foxtrot: Sana Buch, Andrew Duffy, Liliana Gutierrez, Chris Starrick
Purpose of the meeting:
Things seem in "flux"
Establish a feed basis (should be given to team Foxtrot by Monday)
What we need to do:
Send an email to Foxtrot, Shannon and Adam stating the composition and the feed rate required
what contaminants can we ignore?
what will poison our catalyst?
what exactly are our requirements?
Location?? (information needs to be handed over to Foxtrot sometime next week.)
its easier to transfer coal compared to transferring ethylene, so this decision should be made as a joint group.
some locations to look into:
st. louis (marathon petrochemical plants)
do they sell ethylene crackers?
gulf coast
look up where ethylene crackers are readily available
send a few locations to foxtrot so they have a choice as well
Utility conditions?
Are there any conditions that both the teams need?
compare conditions with foxtrot and determine if there is anything we both can use
example: steam pressure levels
What we know:
Echo needs syngas to be at these ranges:
temp: 250-300 C
pressure: 100-300 bar
Echo is using nickel carbonyl and cobalt as catalysts
Foxtrot currently want their gassifier to be located in Illinois # 6 Basin/Butiminous
located in southern illinois

Meeting: January 20, 2011 Working Title: Synthesis of Plastics from Propionic Acid
Design Basis: Why we need to produce plastic. (In Discussion)
Plastics being looked at:
Polyethylene · Polyethylene (or polyethene, polythene, PE) is a family of materials categorized according to their density and molecular structure. For example, ultra-high molecular weight polyethylene (UHMWPE) is tough and resistant to chemicals, and it is used to manufacture moving machine parts, bearings, gears, artificial joints and some bulletproof vests. High-density polyethylene (HDPE) is used to make milk jugs, margarine tubs and water pipes. Medium-density polyethylene (MDPE) is used for packaging film, sacks and gas pipes and fittings. Low-density polyethylene (LDPE) is soft and flexible and is used in the manufacture of squeeze bottles, sacks and sheets.
Teflon · Teflon is the brand name given by DuPont Corp. for a polymer called polytetrafluoroethylene (PTFE), which belongs to a class of thermoplastics known as fluoropolymers. It is famous as a coating for non-stick cookware. Being chemically inert, it is used in making containers and pipes that come in contact with reactive chemicals. It is also used as a lubricant to reduce wear from friction between sliding parts, such as gears, bearings and bushings.
Leaning towards making propionic acid -> polyethylene
Wednesday January 19, 2011 (first meeting as a group) Do some research by second group meeting
Advantages and Disadvantages of gasses being looked into: · Propionic acid: o Naturally occurring o Made from ethylene and carbon monoxide o Uses and advantages: § Analgesic § Intermediate product for thermoplastic · Formic acid: o May cause damage to optic nerves o Made from methanol, ammonia sulfuric acid, and carbon monoxide o Also made from water and carbon monoxide § Cheapest to make? · Operating at a high partial pressure o Simplest carboxylic acid · Acetic acid: o Global demand: 6.5million tonnes/year o Made from carbon monoxide and methanol
Wednesday Conference Meeting 03/30/11
Tuesday Conference Meeting 03/15/11
What is important for process to operate properly
Need schematic of necessary controls in place
ISA symbology
Distillation column- temp, composition, temp chNge, over head reciwver, not dry pump, must have some level in the bottom of the columns, platform wert twenty or thirty feet, platform with ladder

Wednesday 03/09/11 Telecom Meeting
Tuesday 03/08/11 Questions and suggestions made by Mentors:
Presentation questions:
Wednesday 02/23/11 Telecom Meeting
Thursday 02/17/11 Telecom Meeting
Tuesday 02/15/11 Questions and suggestions made by Mentors:
1. Note the sources of the info and numbers brought up
2. Note the $/yr or day or month that are being calculated in the pricing and economics
3. Use scientific notation, commas, an overall number to describe an estimate without many and ongoing significant figures
4. Price of syngas is high...get a better estimate
5. Estimated capital cost is very low, get a better estimate
6. There are equipment/steps needed in the process such as:
decanter
recycle
to recover catalyst on regular basis
something to make sure catalyst doesn't go anywhere wrong
heat removal step
where to flash out product
7. CSTR is a design reactor or are we modeling it like that in aspen?
show what it is/what it's like
8. how do we get aldehyde out of liquid?
9. stick with outline as placed in beginning of presentation
10. include capital cost in a safety system
11. place process overview with total #s in and out
this can be displayed in a diagram
12. improvise the block flow diagram to show what's in the streams and display numbers
